ABSTRACT:
An ultrasonic diagnostic apparatus either for displaying three-dimensional ultrasonic images allowing an operator to become aware of the distance of a target object from an ultrasonic probe, or for displaying practical three-dimensional ultrasonic images while being simply structured and taking a short time to perform necessary operations. The apparatus comprises: an ultrasonic beam data memory for storing B-mode ultrasonic beam data or CFM ultrasonic beam data; an address control unit for sequentially writing and reading the ultrasonic beam data to and from the ultrasonic beam data memory in the direction of depth; a three-dimensional operation unit for generating three-dimensional ultrasonic beam data using the ultrasonic beam data read from the ultrasonic beam data memory by the address control unit; a three-dimensional ultrasonic beam data memory for storing the three-dimensional ultrasonic beam data thus generated; a DSC (digital scan converter) for converting the three-dimensional beam data to a display-ready format; and a CRT.
